Features:
If you’ve added bigger wheels, more power, or put your truck through serious off-road or pulling stress, the factory idler arm just isn’t going to cut it. The PPE Extreme Duty Forged Idler Arm is built to give your Silverado or Sierra HD the steering strength it should have had from the start. Forged steel construction makes it far stronger than stock, while the oversized 7/8 inch bolt assembly provides a rock-solid connection that won’t twist or flex under pressure. Dual replaceable bearings ensure smooth, precise steering feel and long-term durability, even in harsh conditions. Whether you’re daily driving, hitting the dirt, or hooking up to the sled, this upgrade keeps your steering system planted and dependable. Pair it with PPE’s Extreme-Duty Pitman Arm and drilled center link for a full-strength steering solution. It’s a straightforward upgrade that gives you confidence every time you turn the wheel.
The PPE 158041100 Extreme Duty Forged Idler Arm is designed to outperform the factory component in every way on 2011-2025 Silverado and Sierra 2500HD and 3500HD trucks. Built from forged steel, this idler arm resists flexing and distortion under the high loads produced by larger tires and added horsepower. The 7/8 inch bolt assembly provides a much stronger connection compared to stock hardware, reducing steering play and wear over time. Dual bearings are fully replaceable, allowing for extended service life and smoother steering operation. This part is designed to work seamlessly with PPE’s Extreme-Duty Pitman Arm and PPE’s 7/8 inch drilled center link, though it can also be used with a drilled OEM center link when properly modified. The result is a stronger, more stable steering base that’s well-suited for trucks that see racing, sled pulling, or serious off-road use. Backed by a limited lifetime warranty, it’s a long-term solution for steering upgrades.
